Some of the postulates of the VSEPR Theory is- 1) The number of pairs of electrons present on the central atom determines the shape of the covalent molecule. 2) The bonds formed by sharing of electrons are covalent, and these covalent bonds are around the central atom. ...
What is VSEPR theory? Electron Orbitals: Electrons are negatively charged particles that orbit the nucleus of atoms. Since electrons are negatively charged, they repel each other and the arrangement of the electrons will predict the shape of the molecule. ...

We have already covered the Lewis structure and the Valence Bond Theory. Did you get all the answers to your queries? No. We do not know anything about the geometrical arrangement of the various molecules. the VSEPR theory comes to our rescue! In this ch
Though atomic structure and crystal structure are related, they are representationally different. The structure of each is typically represented with drawings and identifying factors. Answer and Explanation: The structure of a substance is a key identification factor. You can distinguish salt from sa...
Lewis structures tell us the electron geometry of a molecule. The molecular geometry of a molecule is determined from its Lewis structure and VSEPR (valence shell electron pair repulsion) theory. The number of bonds and lone pair of electrons around the central atom of a molecule tell us its ...
The simplest molecule has one central atom with two additional atoms bonded to it. According to the VSEPR theory, the two bonded atoms will position themselves as far apart from each other as possible, resulting in a linear molecular shape. The angles between the bonds are 180 degrees. Covalen...
We have been slowly putting together a new chapter to the Physics Tutorial on our site. The new chapter is the first of two chapters to be added on the topic of electromagnetism. This chapter will have four Lessons. We have recently completed Lesson 1 of the Magnetic Fields and ...
and -hedral relates to a face of a solid; “tetrahedral” literally means “having four faces. ” This shape is found when there are four bonds all on one central atom, with no lone electron pairs. In accordance with the VSEPR theory, the bond angles between the electron bonds are 109.5...
